MRI的影像組學(xué)特征與HCC患者TACE術(shù)后無(wú)復(fù)發(fā)生存期的關(guān)系
發(fā)布時(shí)間:2021-01-05 04:07
背景與目的:術(shù)前評(píng)估肝細(xì)胞癌(hepatocellular carcinoma,HCC)經(jīng)常規(guī)導(dǎo)管動(dòng)脈化療栓塞(transcatheter arterial chemoembolization,TACE)術(shù)后復(fù)發(fā)對(duì)治療方案選擇和后續(xù)隨訪至關(guān)重要。探討基于術(shù)前增強(qiáng)磁共振圖像(magnetic resonance imaging,MRI)的影像組學(xué)模型、臨床影像模型和聯(lián)合模型與HCC患者經(jīng)TACE術(shù)后無(wú)復(fù)發(fā)生存期(recurrence-free survival,RFS)的相關(guān)性,并建立影像組學(xué)諾莫圖用于個(gè)體化評(píng)估無(wú)復(fù)發(fā)生存期和復(fù)發(fā)風(fēng)險(xiǎn)分層。材料和方法:本研究總共納入HCC患者184例,所有患者隨機(jī)(7:3)分為訓(xùn)練集(n=110)和驗(yàn)證集(n=74)。構(gòu)建基于瘤體和腫瘤邊界外擴(kuò)(1、3和5mm)的影像組學(xué)標(biāo)簽,使用最小絕對(duì)收縮與選擇算子算法(least absolute shrinkage and selection operator,LASSO)Cox回歸建立影像組學(xué)模型;使用單因素和多因素Cox回歸確立臨床影像特征獨(dú)立風(fēng)險(xiǎn)因子,并通過(guò)多因素Cox比例風(fēng)險(xiǎn)模型建立臨床影像模型;聯(lián)合影像...
